Great Add-On ... but. Rated 2 out of 5 stars

This is a very useful add-on, but ...

It throws errors:
Error: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIStreamListener.onStartRequest]
Source file: file:///C:/Users/Sam/AppData/Roaming/Mozilla/Firefox/Profiles/1un5sfx1.default/extensions/firebug@software.joehewitt.com/components/firebug-channel-listener.js
Line: 144

And this error seems to indicate that Firebug is keeping track of the websites that we are going to ....

Say it ain't so.

Corrupts CSS when inspecting Rated 1 out of 5 stars

Switching to Opera for DragonFly. Inspecting something and changing it's styles corrupts the CSS. I won't be returning to Firefox for a while (this really is a deal-breaker).

Great, but... Rated 4 out of 5 stars

Agreed with Rob, but since Firefox 3.5 and the latest Firebug I had problem with randomly freezing flash apps and videos. After uninstalling, flash was behaving correctly. But Firebug was working great as usual. Thanks

If there were 6 stars, I'd give that. Firebug is simply the best developer addon for any tool that I have ever seen. And I have seen quite a few.

关于HTML源码显示 Rated 5 out of 5 stars

我用的FireFox3.5版本,同时更新了FIREBUG的相应版本,当我启用了"展开更改"或"滚动到更改处"时,下面显示的HTML会不停的闪烁,根本没办法看,不知是何原因.当禁用这两个功能时,就不再闪烁.
谢谢

Hotkeys should be programmable, or we should at least be able to choose whether or not to use them.. I have an undo closed tab function that uses Ctrl+F12 and this overrides it. I disabled firebug because I used Ctrl+F12 for un-closing tabs constantly.

Without doubt one of the most important business tools used by our development company. Improved productivity and JS debugging beyond possibility. Keep up the good work (also maybe better exception stacks for common JS frameworks (MooTools, jQuery EXT?)

Definitely one of the most useful add ons in the world. Some people even keep using Firefox even if they prefer Opera/Chrome just for Firebug! Saves A LOT of time. Thanks!
